How to Make Hair Color Last Longer

To make hair color last longer, wait at least 24 to 48 hours before your first shampoo, wash less often with a sulfate-free shampoo and conditioner made for color-treated hair, treat your hair to a deep treatment, and refresh your tone with a gloss between colorings. Even though permanent color is designed to last, it can still fade and lose tone. Properly caring for your color helps extend the life of your color, keeping it looking fresh, vibrant, and beautiful for longer.

Here is the full routine: what to do before you color, in the first few days after, and in the weeks that follow.

How Long Does Permanent Hair Color Last?

Permanent hair color lasts until it grows out. However, two things change over time: the tone can fade and lose richness and depth, and new uncolored regrowth appears at your roots as your hair grows.

Most people begin to see regrowth in about four to six weeks, sometimes sooner. That is a regrowth timeline, not an expiration date on your color. Your colored lengths are still colored.

So making your color last longer is really two separate jobs: keeping tone rich on the hair you have already colored, and covering new regrowth at the roots. For the regrowth side, see our guide to touching up your roots.

Prep Your Hair Before You Color

Color lasts longer on hair that is already in good condition. The coloring process opens the cuticle to allow pigment to penetrate. An open cuticle also allows moisture to escape. Hair that is dry and porous to begin with, lets color escape faster.

• Deep condition first. In the weeks leading up to your color session, deep condition once or twice a week, or every two to three times you shampoo. Apply a conditioning treatment or mask after shampooing: wring out as much moisture as possible before applying to ensure it absorbs properly into the hair. Be sure to rinse with cool water to lock benefits in.

• Look for strengthening and hydrating ingredients in your hair care products. Sulfate-free, nutrient-rich formulas infused with ingredients like keratin, argan oil, and ginseng root extract help fortify the hair, and stronger hair holds onto color better.

• Choose your color product carefully. Dry, damaged hair struggles to hold onto color, which can push people into coloring more often than they need to. Radiant Hair Color is formulated without ammonia, PPD, resorcinol, parabens, phthalates, gluten, SLS, or titanium dioxide, and infused with keratin, argan oil, and ginseng root extract. 

How Long to Wait Before Washing Your Hair After Coloring

After coloring your hair, wait at least 24 to 48 hours before shampooing again, not counting the initial shampoo rinse you do at the time of application. That gives the cuticle time to close before your next wash and is a great way to minimize fading of your fresh, new color.

Because color needs time to settle into the hair, those first two to three days are important for long-term color longevity. Two additional things help:

• Seal color in. A post-color treatment locks in your color and seals down the cuticle layer. Pro Boost: Seal is antioxidant-rich and made for exactly this purpose.

• Give heat styling a break. Air dry where you can in the first few days. When you do reach for a tool, use a heat protectant and the lowest effective setting. Bonding Time is our leave-in treatment that strengthens hair and rebuild bonds while also serving as a thermal protector.

Wash Less Often, and Shampoo Your Scalp, Not Your Lengths

Every wash takes a little pigment with it. Two or three times a week is plenty for most people, and dry shampoo or a gentle oil-absorbing product covers the days in between. Improper washing of your hair may also affect color fading. So, how should you wash your hair?

How you wash matters as much as how often. Shampoo is for your scalp; your lengths mostly just need the rinse and conditioner.

Focus on applying shampoo to the root area of your hair. This way, you’ll cleanse the scalp where your hair needs cleansing the most. It is not ideal to scrub shampoo through the lengths of the hair which may accelerate color fade. Allowing the shampoo to rinse through the lengths with just a light massage will cleanse the hair just fine.

Choose a Shampoo and Conditioner Made for Color-Treated Hair

Not all shampoos are created equal. They may contain harsh ingredients that can cause color to fade and compromise the overall health of your hair.

Switch to sulfate-free formulas. Harsh sulfates strip color and natural oils together, so look for formulas free of ingredients such as sodium lauryl sulfate, parabens, and phthalates.

ColorSolve™ is our color-protecting shampoo and conditioner. You choose the formula for your hair type and texture, and it cleanses without stripping the color you paid for.

What Conditioner Helps Hair Color Last Longer?

Conditioners that help hair color last longer are sulfate-free, color-protecting, and formulated for color-treated hair.. Color-treated hair is mostly a hydration story: well-moisturized hair holds pigment better, reflects more light, and is easier to style. Three ways to put conditioner to work on your color:

• Condition after every wash. Use a color-protecting conditioner like ColorSolve™ to hydrate your hair and protect it from fading.

• Deep condition on a schedule. A mask or deep conditioner every two to three times you shampoo, distributed evenly through and left on for five to fifteen minutes before rinsing.

• Swap in a color-depositing mask. A color depositing mask like Color Therapy conditions and deposits pigment at the same time, so you are keeping up your color during your regular conditioner step.

Use Cool Water, Especially on the Rinse

Water temperature matters more than most people expect. Hot water opens the cuticle layer of the hair which can cause color to escape or drop from the hair.

Wash with cool or tepid water rather than hot, then finish with a cold shot when you rinse out your conditioner. That final cool rinse helps close the cuticle and seal in both your conditioner and your color.

Water quality counts too. Hard water leaves mineral deposits that dull color and pull blondes toward brass. A shower filter is the simplest fix.

Professional colorists do not apply permanent color all over every time, because it can eventually make color turn dull and too dark. They refresh instead with a semi-permanent color like Color Reviving Gloss, so there is no developer to mix. Use it on color-treated hair to tone, add shine, and bring back faded color. It is not intended for gray coverage or touching up your roots.

Color Reviving Gloss lasts 6 to 8 shampoos. Refresh every three to five weeks, or any time your color starts to look dull or brassy.

Use a gloss on color day too, not only in between

On color day, apply Radiant Hair Color to your roots and Color Reviving Gloss to the mid-lengths and ends, and let them process at the same time. Your roots get full gray coverage. Your mid-lengths and ends get a boost of color and shine instead of another round of permanent color, which is what keeps color from turning flat, too dark, and over-processed.

Use a Color-Depositing Hair Mask

A Color Therapy Mask is a deep conditioning mask that deposits pigment at the same time, so it adds color while it hydrates. Use it in the shower in place of conditioner to keep tone from fading. It is not intended for gray coverage. They’re quick to use and hydrate your hair at the same time, which helps improve the overall condition of your hair.

Red fades fastest, since red molecules are the largest. Putting pigment back with Rubino Mask or Barolo Gloss is the difference between six weeks of red and three.

Protect Your Color from Heat, Sun, and Chlorine

Color fades from the outside in, and three of the biggest stressors have nothing to do with your shampoo.

• Heat styling. Heat makes colored hair brittle and fades it faster. Air dry when you can, and use a heat protectant when you cannot. Go easy in the first week after coloring especially.

• Sun exposure. UV fades color. UV protection, a hat, or a scarf all help if you are going to be out for a while.

• Chlorine, minerals, and salt water. Wet your hair with clean water and coat it with conditioner or a leave-in before you get in, wear a swim cap when you can, and rinse right away afterward.

How to Make Semi-Permanent Hair Dye Last Longer

Semi-permanent color is deposit-only. It does not mix with developer, so it sits on the outside of the hair rather than depositing deep inside the cuticle layer, and it washes out gradually instead of growing out. Everything above still applies, and washing habits matter even more:

• Wait 24 to 48 hours before your first wash after applying.

• Wash as infrequently as you can, and use cool water every time.

• Skip clarifying and sulfate-based shampoos, which lift semi-permanent pigment quickly.

• Re-deposit tone before it fully fades. A color-depositing mask between applications keeps the color looking balanced and fresh.

Our semi-permanent option is Color Reviving Gloss, which tones and adds shine to color-treated hair but is not intended for gray coverage. If you want longer-lasting deposit-only color that still washes out gradually, ColorWonder™ demi-permanent color lasts up to 25 washes and is best for all-over color and blending grays on hair that is about 25% gray or less.

The Takeaway

Color that lasts starts with the right formula and stays that way with the right routine. Give fresh color time to settle before your first wash, keep your washing gentle and sulfate-free, condition every time, and refresh your tone with a gloss between colorings. This is the difference between color you love for a few weeks and color you love right up until it grows out.
